Selecting Items From A List And Displaying Related Info
Jun 11, 2011I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.
What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.
Here's the code I've written that successfully imports the data and displays the first column:
Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dataCountry As New DataTable()
[Code]...
Should I perhaps use something other than a list view?

Jul 19, 2010I have a list with a boolean value as one of the properties. I need to check if every one of these is true. Now normally LINQ would give a nice clean answer here, but as I am using .NET 2.0 I can't use that.If there a nicer way to do this or am I going to have to do a for each loop and break out on finding a false?
Edit:Seems I could have been a bit clearer. I have an object in a list (eg List (Of MyObject)). There is a boolean property on this object called Processed.I need to check that all objects in the list are processed.So in LINQ I'd do:if (from o in list where o.processed = false select o).count = 0 then....

Asp.net - List Box Selected Index - Various Items Inserted Depending On The User Selection
Jan 18, 2012I seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.
Change The Background Color Of A Node That Is Being Hovered Over While The User Is Dragging Items From A List Box?
Jul 26, 2009I'm trying to change the background color of a node that is being hovered over while the user is dragging items from a list box.I've gotten both functions to work separately, but while the user is dragging, the NodeMouseHover event does not fire. Is there a way to do both?

Limit Items In Datalist?
Aug 8, 2011how I would put a maximum of rows in a datalist. I have the program reading from a db and I just need to limit the amount of users in the view. The database is organizing the users according to rank and I have it so that it will read the users by rank in descending order (highest rank 1st) I need to limit it to 5 users. Is there a method for this? P.S. I put this here because I know that this is more of a vb.net code oriented question(limiting amount of data shown by an object)

View 2 RepliesAsp.net - ListBox Items Not Selecting ?
Jun 27, 2011I have a simple ASPX page with a listbox and a button. Listbox has about 8-10 items in it. After the user selects an item (listbox is multi-select) and clicks the button, I'm iterating through the items to get the selected one like so:
For Each Item As ListItem In lstLetters.Items
If Item.Selected Then
Dim LetterID As String[code]....
When I step through the code, I select the first item from the listbox. I setup a watch on the 'Item' variable. The code will iterate through each of the items -- but Item.Selected always reads 'False'.I double-check the page, and sure enough my item is selected on the form.What the heck is going on?
